Bold Statements
We’re regularly asked to review IPv6 address plans from different organizations and I’d like to share some reflections from such a process currently happening. I’ve discussed a few aspects of IPv6 address planning before; those readers interested please see this post which contains some references.

Continue readingSome years ago Christopher wrote two posts (2016, 2015) about the IPv6-related characteristics of the WiFi network at Cisco Live Europe. To somewhat continue this tradition and for mere technical interest I had a look at some properties of this year’s setting.

While thinking about the agenda of the upcoming Troopers NGI IPv6 Track I realized that quite a lot of IPv6-related topics have been covered in the last years by various IPv6 practitioners (like my colleague Christopher Werny) or researchers (like my friend Antonios Atlasis). In a kind of shameless self plug I then decided to put together of list of IPv6 talks I myself gave at several occasions and of publications I (co-) authored. Please find this list below (sorted by years); you can click on the titles to access the respective documents/sources.
I hope some of this can be of help for one or the other among you in the course of your own IPv6 efforts.
Cheers,
Enno

Continue readingLast week Will “harmj0y” Schroeder published an excellent technical article titled “Not A Security Boundary: Breaking Forest Trusts” in which he lays out how a highly critical security compromise can be achieved across a forest boundary, resulting from a combination of default AD (security) settings and a novel attack method. His post is a follow-up to the DerbyCon talk “The Unintended Risks of Trusting Active Directory” which he had given together with Lee Christensen and Matt Nelson at DerbyCon (video here). They will also discuss this at the upcoming Troopers Active Directory Security Track (details on some more talks, including Sean Metcalf’s one, can be found in this post or this one).

Continue readingThis is the first post discussing talks of the Active Directory Security Track of this year’s Troopers which took place last week in Heidelberg (like in the last nine years ;-). It featured, amongst others, a new track focused on Microsoft AD and its security properties & implications. This was the agenda.

At Troopers18 there will be a new special track on Microsoft Active Directory and its security aspects, similar to the SAP security track which we established some years ago. The AD security track will feature, amongst others, the following talks.

Continue readingLooking at IPv6 deployment graphs like this one it becomes clear that IPv6 still is not widely deployed in enterprise space (the reason for the apparent oscillation in that curve is the difference between working days – where people use their office computers – and weekend where they preferably use their smartphones or their home equipment connected by means of broadband networks).

Continue readingA while ago I wrote a short paper laying out options for an enterprise organization to get global IPv6 address space from the RIPE NCC, discussing the advantages and disadvantages of different approaches. As I think the topic may be of interest for others, too, I’ve distilled an anonymized version. It can be found here. I hope some of you find it useful.
